Some cars are all over the place. Then there are cars, like the Mitsubishi Diamante, that were supposed to be all over the place but aren't. What's the worst selling volume car ever?

Automakers always have high hopes and forecasts for their bread and butter models, their Camry and Accord competitors. But sometimes they flop and fail. And I mean fail to the point where they sell basically zero.

Now, we aren't looking for some Sultan of Brunei one-off or a limited run supercar. We want cars that sold in big numbers and were huge disappointments. What do you say is the worst selling car of all time?
